INSTALLATION
A. General:
1. Install where indicated, specified, or required in accord with flashing manufacturer's
written instructions and as follows.
2. Extend flashing 6" minimum beyond opening. Fold flashing ends at end of openings or
horizontal flashing terminations to form end dam or use pre-manufactured end dams.
3. Flashing width: Width required starting flush with outside face of exterior wythe,
extending through cavity, rising height required to extend above lintel steel at least 2".
4. Splice end joints by overlapping them 6” and seal with a compatible sealant or metal lap
tape.
5. Masonry back up:
a. Surface apply after dampproofing installation specified in Dampproofing Section in
accord with manufacturer’s installation instructions.
b. Fasten to masonry back-up surface at top by embedding in layer of sealant or use a
non-corrosive termination bar and fasten it to the backer wall at the top edge of the
flashing and seal the top edge with compatible sealant.
6. Concrete back up:
a. Surface apply after dampproofing installation specified in Dampproofing Section in
accord with manufacturer’s installation instructions.
b. Fasten to concrete surface at top by embedding in layer of sealant or use a noncorrosive termination bar and fasten it to the backer wall at the top edge of the
flashing and seal the top edge with compatible sealant or use the termination clamp,
which is embedded in the block back up wall.
7. Stud back up with sheathing:
a. Fasten to stud back-up at top by embedding in layer of sealant or use a non-corrosive
termination bar and fasten it to the backer wall at the top edge of the flashing and seal
the top edge with compatible sealant.
8. Leave ready for certified compatible building felt or air barrier installation lapping
flashing top installed in another Section.
9. Lay flashing in continuous bead of sealant on masonry supporting steel.
10. Fold ends of flashing at end of opening to form dam; seal with sealant or use
manufacturers preformed end dams.
11. Inside corners: Make in industry accepted manner using corner and splice material or use

pre-manufactured corners from manufacturer.
Outside corners: Make in industry accepted manner using corner and splice material or
use pre-manufactured corners from manufacturer.
Cover flashing within a few days of installation to protect it from damage from the
different trades, the environment and falling debris. If flashing is left unprotected and it is
punctured, torn, or has loose scrim you should contact the manufacturer for repair
instructions.
